HIIT and Keto diets

Hi,
I was wondering would if it would be possible to do HIIT on a Keto diet? The reason i ask this is because HIIT relies on muscle glycogen for fuel, now on a Keto diet Glycogen stores are depleted, so would muscle be burned?

If that is the case can i have a protein shake imediatley before HIIT to spare muscle and would this throw me out of ketosis?

You can do HIIT on keto. Just limit yourself to 3 sessions a week and do them during or just after your carb-ups or after a midweek carb-up/refeed. Other times lower intensity and duration are best in a carb dpleted state.
